Classification of illicit liquors based on their geographic origin using Attenuated total reflectance (ATR) – Fourier transform infrared (FT-IR) spectroscopy and chemometrics
Three handheld spectrometers, near-infrared (NIR), Raman and attenuated total reflectance Fourier transform-infrared (ATR-FT-IR) spectroscopy, were used for the identification of ‘legal high’ model mixtures and Internet products.
